Normalized Fuchsian form on Riemann sphere and differential equations for multiloop integrals

Roman N. Lee, Andrei A. Pomeransky

We consider the question of reducibility of the differential system to normalized Fuchsian form on the Riemann sphere. The differential equations for the multiloop integrals in $ε$ …

The $n_{f}^{2}$ contributions to fermionic four-loop form factors

Roman N. Lee, Alexander V. Smirnov, Vladimir A. Smirnov +1

We compute the four-loop contributions to the photon quark and Higgs quark form factors involving two closed fermion loops. We present analytical results for all non-planar master…
